[Rhythmic activity of individual elements of the isolated carp retina].

At the level of photoreceptor, bipolar and ganglion cells of the carp isolated retina displayed intracellular oscillations of two types: with frequency of about 6-12 Hz, continuously generated in darkness, suppressed by light and slowly recovering, and oscillations with frequency of about 20-50 Hz, observed during swithching on and off of light. The latter are components of responses to light of bipolar, amacrine, and ganglion cells. Possible role of different structures of the retina in generation of rhythmic potentials, and their functional significance are discussed.
